StrictFilePathMarshaler must be used on a FilePath

[michaelnoonan]

One of our developers was consistently getting this error when building in Visual Studio 2015: Could not determine assembly version: StrictFilePathMarshaler must be used on a FilePath

I can see some references to this in libgit2sharp, and one in #652.

The only remedy we could find under pressure was to re-clone the repository.

Unfortunately we needed to keep moving and don't have the repository to reproduce it any more. Hopefully if anyone else gets this error message we can narrow down the root cause.

Gathering this is on the GitVersionTask only? I wonder if it is another bug/error which is being triggered which stops the task from generating the version number and then causes this. Hopefully the underlying bug will get found via the exe and fixed then this goes away.

I might close this issue for now, if anyone hits this then post and we can reopen to investigate.

[andrejohansson]

I have this error now on a cleanly installed Windows 10 machine with latest stable git and Visual Studio 2015 enterprise.

Suggestions how I can narrow it down?

[asbjornu]

@andrejohansson It would be nice to know if you use GitVersionTask or gitversion.exe. If you use the former, output from MSBuild would be nice. Run msbuild.exe from the command line if you don't get any valuable build output in Visual Studio. If you use the latter, it should give you build output directly that will be valuable. Any build output you can get your hands on, post it here in a comment.

I'm using the gitversiontask, this is from my csproj file:

  <Error Condition="!Exists('..\packages\GitVersionTask.3.1.2\Build\portable-net+sl+win+wpa+wp\GitVersionTask.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\GitVersionTask.3.1.2\Build\portable-net+sl+win+wpa+wp\GitVersionTask.targets'))" />
  </Target>

  <!-- To modify your build process, add your task inside one of the targets below and uncomment it. 

Here is the build output from within visual studio;

@andrejohansson Could you please do msbuild <solution.sln> on the command line so we get the full build output? The lines written by GitVersionTask are the ones I'd like to see. Use the "Developer Command Prompt for VS2015" or similar for older versions of Visual Studio to have MSBuild added to your PATH.

[asbjornu]

@michaelnoonan, @andrejohansson Poke. 😄

[michaelnoonan]

Hi everyone. I've just had this reoccur, and I realised that repo was still using GitVersionTask.3.1.0 which was lossy - it would just write ex.Message instead of the full exception with stack trace.

Unfortunately upon upgrading to use GitVersionTask.3.4.1 the problem isn't happening any more. I say unfortunately because I was looking forward to getting to the bottom of this issue, but I can't tell for sure, because my git repository has changed state due to upgrading GitVersionTask.

Next time this happens (if ever) I'll be sure to post more details.

[michaelnoonan]

Happy, but sad - it's failed again today! This is now running GitVersionTask.3.4.1.

Interestingly, running a build from the command-line works perfectly, no warnings/errors: msbuild .\source\OctopusDeploy\OctopusDeploy.sln

I don't have much time to investigate further right now, but let me know if there's anything else I can do to help!

@nulltoken Do you have any idea what might be causing this?

[nulltoken]

That reminds me of two ancient issues.

• One was a marshalling issue that led to Generate a unique ID at compile time to work around a CLR bug libgit2/libgit2sharp#438 (was happening when more than one LibGit2sharp was loaded in memory and the callback from native land was picking the wrong one IIRC).
• The other one was FilePathMarshaler must be used on a FilePath libgit2/libgit2sharp#241

How can one ensure GitVersionTask is actually leveraging the LibGit2Sharp version it's bundled with?

@michaelnoonan Is this still a problem, or has it vanished in later versions of GitVersion?

[michaelnoonan]

We have had sporadic recurrences of this problem, but I'm hearing less than
previously. I will update our develop branch to the latest GitVersion and
will report back if it recurs again.
